Description

Technical Field

[0001] This application relates to the technical field of clamping fixtures, and in particular to a quick clamping fixture for heat-treated parts. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which the chemical composition and structure of a metal material are changed on its surface or inside by means of heating, holding and cooling in the solid state, so as to obtain the desired properties. For the heat treatment of a large number of different types of parts, the clamping efficiency and stability of the parts directly affect the production efficiency and product quality of heat treatment.

[0003] The existing publication number CN221159118U, entitled "A Clamping Fixture," includes a bearing base. A bent frame, rotatably connected to a lead screw, is rotatably mounted between two opposing inner walls of the bearing base. A clamping mechanism is arranged on opposite sides of the top of the bent frame. The clamping mechanism includes a housing with a mounting groove, several clamping plates, and connecting balls fixedly connected to the clamping plates. Several spherical sleeves, movably connected to the connecting balls, are arranged inside the mounting groove. A spring is located on both sides of the spherical sleeves and between the clamping plates and the inner wall of the mounting groove. This utility model clamping fixture can adapt to the side walls of different workpieces, ensuring a tight fit with the workpiece side walls and improving clamping stability.

[0004] Regarding the aforementioned technologies, the inventors discovered that when the parts are subjected to heat treatment and clamping, the end face of the clamping plate that holds the heat-treated parts is set vertically and horizontally. Since the parts have different shapes during heat treatment, the single vertical and horizontal clamping of the clamping plate cannot meet the clamping requirements of parts with different shapes, which results in a small applicable range for parts clamping and heat treatment. Utility Model Content

[0005] In order to overcome the limitations of existing clamping methods where the clamping plates for heat-treated parts are set vertically and horizontally, and where the shapes of parts vary during heat treatment, the single vertical and horizontal clamping method cannot meet the clamping requirements of parts with different shapes. This results in a limited range of applications for clamping parts for heat treatment. Therefore, this application provides a quick clamping fixture for heat-treated parts.

[0006] The quick clamping fixture for heat-treated parts provided in this application adopts the following technical solution:

[0007] A quick clamping fixture for heat-treated parts includes a support, an opening / closing component, and clamping components. The support includes a bracket with a rotating seat vertically fixed through the center of its top surface. Multiple fixing screws are horizontally fixed to the bottom of both sides of the bracket. The opening / closing component includes an opening / closing slide frame, which is horizontally rotatably positioned above the bracket. A bidirectional screw is horizontally rotatably connected inside the opening / closing slide frame, and an opening / closing motor is horizontally fixed to the end of the opening / closing slide frame. The output end of the opening / closing motor is fixedly connected to the end of the bidirectional screw. Two clamping components are symmetrically and vertically arranged inside the opening / closing slide frame. Each clamping component includes a first screw hole slider, a lifting frame, a hole seat, and a pressure post. The first screw hole slider is horizontally slidably assembled in the opening / closing slide frame, and a lifting frame is vertically fixed to the top surface of the first screw hole slider. A hole seat is vertically slidably assembled in the lifting frame, and multiple pressure posts are horizontally inserted through the top of the hole seat.

[0008] By adopting the above technical solution, in order to clamp and install heat-treated parts, the opening and closing motor at one end of the opening and closing slide frame is started. The opening and closing motor drives the bidirectional screw to rotate. The bidirectional screw thread drives the slider of the bottom first screw hole in the two clamping parts in the opening and closing slide frame to slide horizontally. This causes the pressure column in the hole seat of the two clamping parts to press against the outer wall of the heat-treated part. The pressure column moves laterally in the hole seat. The pressure column is suitable for the needs of heat-treated parts with different shapes and structures. Therefore, the parts have different shapes during heat treatment. The pressure column moves laterally in the hole seat and is suitable for the needs of heat-treated parts with different shapes and structures. This makes it suitable for clamping parts with different shapes and structures, which improves the applicability of parts clamping for heat treatment.

[0009] Optionally, a baffle is horizontally fixed on the outer end face of the hole seat, and multiple damping rods are horizontally fixed on the inner wall of the baffle, and the multiple damping rods are fixedly assembled with the ends of multiple pressure columns one by one.

[0010] By adopting the above technical solution, multiple damping rods are horizontally arranged between the hole seat and the retaining frame. The multiple damping rods, together with multiple pressure columns, are used to buffer the vibration that occurs during the heat treatment of the clamped parts, so as to ensure the stability of the parts during the heat treatment.

[0011] Optionally, each of the ends of the multiple pressure columns is fixed with a pressure spring, and the other end of the pressure spring is fixed to the inner wall of the baffle frame. The other end of each of the multiple pressure columns is horizontally fixed with a rubber block.

[0012] By adopting the above technical solution, in order to ensure the stability of the parts during heat treatment, the deformation force of the compression spring is used to push multiple compression columns to slide in the hole seat. The deformation force of the compression spring causes multiple compression columns to press against the parts. During heat treatment, the parts vibrate, causing the spring to deform. The deformation potential energy of the spring is canceled by multiple damping rods, thus ensuring the stability of the parts during heat treatment.

[0013] Optionally, a bracket is vertically fixed on the bottom surface of the opening and closing slide frame, and a rotating rod is vertically fixed on the bottom surface of the bracket, and the rotating rod is rotatably connected to the rotating seat.

[0014] By adopting the above technical solution, the bottom surface of the bracket fixed to the bottom surface of the opening and closing slide frame is rotatably connected to the rotating seat, which facilitates the opening and closing slide frame to deflect on the rotating seat and horizontally switch the clamping direction of the opening and closing slide frame.

[0015] Optionally, a driven gear is horizontally fixed on the bottom end face of the rotating rod.

[0016] By adopting the above technical solution, the driven gear fixed at the bottom of the rotating rod facilitates the rotation of the opening and closing slide frame on the bracket, and horizontally switches the angle of the part clamping heat treatment.

[0017] Optionally, a flip motor is vertically fixed on the bottom surface of the bracket, and a drive gear is horizontally fixed at the output end of the flip motor, with the drive gear meshing with the driven gear.

[0018] By adopting the above technical solution, the flipping motor on the starting bracket drives the active gear to rotate. The active gear meshes with the driven gear, driving the rotating opening and closing slide frame on the bracket to horizontally switch the angle of the part clamping heat treatment.

[0019] Optionally, a second screw hole slider is vertically fixed on the bottom surface of the hole seat, and the second screw hole slider is vertically slidably installed on the lifting frame.

[0020] By adopting the above technical solution, the second screw hole slider fixed on the bottom end face of the hole seat is vertically slidably installed in the lifting frame, which facilitates the vertical sliding drive of the hole seat to move vertically in the lifting frame and adjust the height of the clamped parts.

[0021] Optionally, a lifting screw is vertically rotatably connected to the lifting frame, and the lifting screw is threadedly connected to the second screw hole slider.

[0022] By adopting the above technical solution, a rotating lifting screw is used to rotate in the lifting frame. The lifting screw and the second screw hole slider are threaded together and assembled. The second screw hole slider, which is fixed on the bottom surface of the drive hole seat, is vertically slidably installed in the lifting frame, which facilitates the vertical sliding drive hole seat to move vertically in the lifting frame and adjust the height of the clamped parts.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, to clamp and install heat-treated parts, the opening and closing motor at one end of the opening and closing slide frame is activated. The opening and closing motor drives the bidirectional screw to rotate. The bidirectional screw thread drives the slider of the bottom first screw hole in the two clamping members of the opening and closing slide frame to slide horizontally, causing the pressure column in the hole seat of the two clamping members to press against the outer wall of the heat-treated part. The pressure column moves laterally in the hole seat. The pressure column is suitable for heat-treated parts with different shapes and structures, thus improving the applicability of part clamping for heat treatment due to the different shapes of the parts during heat treatment.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a quick-clamping fixture for heat-treated parts. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A quick-clamping fixture for heat-treated parts includes a support 1, an opening / closing component 2, and a clamping component 3. The support 1 includes a bracket 11, with a rotating base 13 vertically fixed through the center of its top surface. Multiple fixing screws 12 are horizontally fixed to the bottom of both sides of the bracket 11. The opening / closing component 2 includes an opening / closing slide frame 21, which is horizontally rotatably positioned above the bracket 11. A bidirectional screw 22 is horizontally rotatably connected inside the opening / closing slide frame 21, and an opening / closing motor 23 is horizontally fixed to the end of the opening / closing slide frame 21. The output end of the opening and closing motor 23 is fixedly connected to the end of the bidirectional screw 22. Two clamping parts 3 are symmetrically and vertically arranged inside the opening and closing slide frame 21. The clamping parts 3 include a first screw hole slider 31, a lifting frame 32, a hole seat 35 and a pressing column 37. The first screw hole slider 31 is horizontally slidably assembled in the opening and closing slide frame 21, and the lifting frame 32 is vertically fixed on the top surface of the first screw hole slider 31. The hole seat 35 is vertically slidably assembled in the lifting frame 32, and multiple pressing columns 37 are horizontally inserted through the top of the hole seat 35.

[0032] By adopting the above technical solution, in order to clamp and install heat-treated parts, the opening and closing motor 23 at one end of the opening and closing slide frame 21 is activated. The opening and closing motor 23 drives the bidirectional screw 22 to rotate. The bidirectional screw 22 drives the bottom first screw hole slider 31 of the two clamping parts 3 in the opening and closing slide frame 21 to slide horizontally, which drives the pressure column 37 in the hole seat 35 of the two clamping parts 3 to press against the outer wall of the heat-treated part. The pressure column 37 moves laterally in the hole seat 35. The pressure column 37 is suitable for the needs of heat-treated parts with different shapes and structures. Thus, the parts have different shapes during heat treatment. The pressure column 37 moves laterally in the hole seat 35 and is suitable for the needs of heat-treated parts with different shapes and structures. It is suitable for clamping parts with different shapes and structures, which improves the applicability of parts clamping for heat treatment.

[0033] Reference Figure 5 A retaining frame 36 is horizontally fixed to the outer end face of the hole seat 35, and multiple damping rods 38 are horizontally fixed to the inner wall of the retaining frame 36. Each damping rod 38 is fixedly assembled with the ends of multiple pressure posts 37. Multiple damping rods 38 are horizontally arranged between the hole seat 35 and the retaining frame 36. These damping rods 38, in conjunction with the multiple pressure posts 37, buffer the vibrations that occur during heat treatment of the clamped parts, ensuring the stability of the parts during heat treatment. Each end of the multiple pressure posts 37 is fixed with a pressure spring 39, and the other end of the pressure spring 39 is fixed to the inner wall of the retaining frame 36. A rubber block 371 is horizontally fixed to the other end of each of the multiple pressure posts 37. To ensure the stability of the parts during heat treatment, the deformation force of the compression spring 39 is used to push multiple compression columns 37 to slide in the hole seat 35. The deformation force of the compression spring 39 causes the multiple compression columns 37 to press against the parts. During heat treatment, the parts vibrate, causing the spring 39 to deform. The deformation potential energy of the spring 39 is canceled by multiple damping rods 38, ensuring the stability of the parts during heat treatment.

[0034] Reference Figure 3 and Figure 4 A bracket 24 is vertically fixed to the bottom surface of the sliding frame 21, and a rotating rod 25 is vertically fixed to the bottom surface of the bracket 24, with the rotating rod 25 rotatably connected to the rotating base 13. The rotating rod 25 on the bottom surface of the bracket 24, fixed to the bottom surface of the sliding frame 21, rotatably connects to the rotating base 13, facilitating the deflection of the sliding frame 21 on the rotating base 13 and horizontally switching the clamping direction of the sliding frame 21. A driven gear 26 is horizontally fixed to the bottom end surface of the rotating rod 25. The driven gear 26 fixed to the bottom end of the rotating rod 25 facilitates driving the sliding frame 21 to rotate on the bracket 11, horizontally switching the angle of the heat-treated parts clamping.

[0035] A tilting motor 14 is vertically fixed on the bottom surface of the bracket 11, and a drive gear 15 is horizontally fixed at the output end of the tilting motor 14, with the drive gear 15 meshing with the driven gear 26. In use, starting the tilting motor 14 on the bracket 11 drives the drive gear 15 to rotate, and the drive gear 15 meshes with the driven gear 26, driving the rotating sliding frame 21 on the bracket 11 to horizontally switch the angle of the part clamping heat treatment.

[0036] Reference Figure 3 A second screw-hole slider 34 is vertically fixed to the bottom surface of the hole seat 35, and the second screw-hole slider 34 is vertically slidably mounted on the lifting frame 32. The second screw-hole slider 34, fixed to the bottom surface of the hole seat 35, is vertically slidably mounted on the lifting frame 32, facilitating the vertical sliding drive of the hole seat 35 within the lifting frame 32 to adjust the height of the clamped part. A lifting screw 33 is vertically rotatably connected to the lifting frame 32, and the lifting screw 33 is threadedly connected to the second screw-hole slider 34. During use, rotating the lifting screw 33 within the lifting frame 32, with the lifting screw 33 and the second screw-hole slider 34 threadedly connected, drives the second screw-hole slider 34, fixed to the bottom surface of the hole seat 35, to slide vertically within the lifting frame 32, facilitating the vertical sliding drive of the hole seat 35 within the lifting frame 32 to adjust the height of the clamped part.

[0037] The implementation principle of a quick clamping fixture for heat-treated parts in this application embodiment is as follows: During use, to clamp and install heat-treated parts, the opening and closing motor 23 at one end of the opening and closing slide frame 21 is activated. The opening and closing motor 23 drives the bidirectional screw 22 to rotate. The bidirectional screw 22 threadedly drives the bottom first screw hole slider 31 of the two clamping members 3 in the opening and closing slide frame 21 to slide horizontally, causing the pressing column 37 in the hole seat 35 of the two clamping members 3 to press against the outer wall of the heat-treated part. The pressing column 37 moves laterally in the hole seat 35. The pressing column 37 is suitable for heat-treated parts with different shapes and structures. To ensure the stability of the part during heat treatment, the deformation force of the pressing spring 39 pushes multiple pressing columns 37 to slide in the hole seat 35. The deformation force of the pressing spring 39 causes multiple pressing columns 37 to press tightly against the part. During heat treatment, the part vibrates, causing the spring 39 to deform. The deformation potential energy of the spring 39 is offset by multiple damping rods 38, ensuring the stability of the parts during heat treatment. Thus, the parts have different shapes during heat treatment. The pressure column 37 moves laterally in the hole seat 35. The pressure column 37 is suitable for heat treatment parts with different shapes and structures, and can be used to clamp parts with different shapes. The flip motor 14 on the start bracket 11 drives the drive gear 15 to rotate. The drive gear 15 meshes with the driven gear 26, driving the rotating opening and closing slide frame 21 on the bracket 11 to switch the angle of the parts clamped for heat treatment horizontally. The lifting screw 33 rotates in the lifting frame 32. The lifting screw 33 and the second screw hole slider 34 are threaded through and assembled. The second screw hole slider 34, which is fixed on the bottom surface of the drive hole seat 35, is vertically slidably installed in the lifting frame 32, which facilitates the vertical movement of the drive hole seat 35 in the lifting frame 32 to adjust the height of the clamped parts.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
